Abstract
The invention relates to a method for calculating a first identifier of a secure element of a mobile terminal according to a second identifier of said secure element. The first identifier is a temporary identifier and the second identifier is a final identifier of the secure element in a telecommunications network. According to the invention, the method comprises the steps of: a—during the first attempt to connect the mobile terminal to the telecommunications network, calculating the first identifier according to the second identifier; b—transmitting the first identifier to the telecommunications network; c—in response to a message of acceptance of the first identifier from the telecommunications network, inhibiting the use of the first identifier by the secure element and, for every subsequent attempt to connect to the telecommunications network, using the second identifier to authenticate the secure element.
